Claims. (Cl. 240-146) This invention relates generally to ceiling typeelectric light fixtures and more particularly to improved means formounting the shade of such a fixture.

A principal object of the present invention is to provide means forsuspending the shade of a ceiling type electric light fixture wherebyused electric light bulbs can be conveniently replaced with a minimumexpenditure of time and effort.

Other objects and advantages of the present invention will appear morefully hereinafter, it being understood that the invention consistssubstantially in the combina tion, construction, location and relativearrangement of parts, all as described in the accompanying drawings andas finally pointed out in the appended claims.

In the accompanying drawings:

Figure l is a vertical section taken through a ceiling type electriclight fixture constructed in accordance with and embodying theprincipals of the present invention;

Figure 2 is the same as Figure 1, however, the shade has been dropped tofacilitate changing the electric light bulb;

Figure 3 is the same as Figure 2, however, the shade is shown cantedtoward one side;

Figure 4 is an enlarged section taken on line 4-4 of Figure 2;

Figure 5 is an enlarged section taken on line 55 of Figure 1; and

Figure 6 is a section on line 66 of Figure 4.

Referring particularly to Figure 1, the electric light fixtureconstructed in accordance with and embodying the principles of thepresent invention comprises a canopy 1i,- and an assembly 11 thatdepends from the canopy 16 and which has a glass bowl or shade 12mounted upon the lower end thereof in underlying relation to an electriclight bulb 13.

Referring particularly to Figure 5, it will be observed that theassembly 11 comprises an adapter sleeve 14 having a large diameter upperend portion 15 which is internally threaded and turned onto the lowerextremity of a tubular member 16 secured to and depending from thecanopy 10, as well as a small diameter lower end portion or nipple 17which is externally threaded for receiving a cap nut 18. The shade 12 iscentrally apertured and loosely fitted over the lower end portion 17 ofthe adapter sleeve 14. The bowl 12 rests directly upon a felt washer 19that is located inside a decoratively dished washer 20, and just abovethe base wall of the bowl 12 is a second felt washer 19. The cap nut 18is threaded onto the adapter sleeve 14 a distance sufiicient forclamping the washers 1919 and 20 and the shade 12 between the cap nut 18and an annular shoulder 21 that is formed on the underside of the upperend portion 15 of the adapter sleeve 14.

Threaded into the crown of the cap nut 18 is the lower end portion of arigid rod 22 that extends upwardly freely through the adapter sleeve 14and into the tubular member 16, terminating in a free end portion whichis pro- 2,820,888 Patented Jan. 21, 1958 vided with a pair of lateralprotuberances 23-23 extending outwardly in opposite directions. This rod22 is fixedly secured to the cap nut 18 for rotation therewith, the rod22 being thus freely rotatable in the tubular member 16 upon turning thecap nut 18 in either direction.

Formed within the adapter sleeve 14 just below the lower end of thetubular member 16 is an internal flange 24 providing a restrictedpassage therethrough of a diameter substantially less than that of thetubular member and of the section of the passage through said adaptersleeve located below the flange 24, said passage being so reduced as toprevent complete separation of the rod 22 downwardly from the adaptersleeve 14 (see Figure 4).

Referring particularly to Figures 1 and 5, when it becomes necessary toreplace the electric light bulb 13 or to clean the interior of the shade12, it is only required tounscrew the cap nut 18, whereupon the assemblycomprising the cap nut 18, the rigid rod 22, the washers 19-19 and 20and the shade 12 may be lowered as a unit to the position shown inFigures 2 and 4, wherein the protuberanccs 23-23 provided on the upperend of the rod 22 are seated upon the annular formation 24 Within theadapter sleeve 14. It will be appreciated that with the shade suspendedin the manner described at an increased distance from the canopy,sufiicient access is provided between the shade and the canopy forconvenient removal and replacement of the light bulb 1 3 and forcleaning the internal surface of the shade.

It will be noted that even greater access may be had to the interior ofthe shade by simply tilting the suspended assembly as shown in Figure 3.in performing these operations, the shade remains safely suspended fromthe canopy and is readily replaced in secure position by shifting itvertically into its normal position shown in Figure l to permitre-engagement of the cap screw 18 with the threaded nipple 17 of theadapter sleeve 14.

It will be understood, of course, that the present in vention ashereinbefore described and shown in the accompanying drawings issusceptible of various changes and modifications which may be made fromtime to time without departing from the general principles or realspirit of the invention, and accordingly, it is intended to claim thesame broadly, as well as specifically, as indicated by the appendedclaims.

What is claimed as new and useful is:

1. in a device for mounting the shade of a ceiling type electric lightfixture, a tubular member, an elongated rigid element freely projectedinto one end of said member, means securing corresponding end portionsof said tubular member and rigid element together, an electric lightshade seated upon said securing means, said securing means beingdetachable from said tubular member, and the assembly including saidsecuring means, rigid element and shade being thereupon shiftable as aunit into axial extension of said tubular member, and means securingsaid tubular member and rigid element against disassembly and therebylimiting the movement aforesaid of said assembly relative to saidtubular member.

2. In a device for mounting the shade of a ceiling type electric lightfixture, a tubular member, an adapter sleeve fitted over one end portionof said tubular member and having a circumferentially extending externalshoulder intermediate the opposite ends thereof, a cap element fittedover a reduced diameter end portion of said adapter sleeve, a rigid rodfixedly secured to said. cap element and freely projected through saidadapter sleeve and into said tubular member, an electric light shadeseated upon said cap element and clamped thereby against said adaptershoulder, said cap element being de'tachahle:,-fromssaideadapteresleeve, (and theeassemblymincluding saidcap element, rigid rod and shade being thereupon shiftable as a unitinto axial extension of saidv d p el ment1aud rredue zd ametereendspert-ion l-of -111 lexipe tor menntinga he shadetof ae iling yp m niaiada te sle :lA YiP enipqzt am V ame d-b d es ofls i aw ar m mbe nd atest-pa e aii'rwrfim e nd n 4P 1pneitudin i entin ti n41 sai tubulmember, a ,,l east.,,a portion of said-,adapter beyond ,the end of saidtubular. member beingfprovided with en internal diameer,;than.. that ,of,said tubular memgberfto thereby iqrrn ,anaunul-arinternal seat a vcaptree end ,por'tipnof said r o,d ,heinglaterally expanded t9 p ecludewifladra .ths sef tbwlel iih t m internal fi xne e flfi n-i r aiadapterskex and .fo w ng n movement of the lower end. portion of saidrodffrom ,side to side when said expanded freee'nd' portionpfthe rod isengaged With theannular internalseat aforesaid, an '-electric"light-shade seated uponsaid cap elemenflthelatter being detachable fromsaid' adapter sleeve, and the as- '-sernbly including said gap element,rigid rod-and shade being thereupon --shi-ftab1e within "a predeterminedr a nge .vas.aeunit.intoeaxiaLextension1of .said tubular-member andadapter sleeve and from side to side.
